The team, comprising of Trivikram Annamalai and Aditya Gupte from IIT-Bombay, Anchit Srivastava from Mumbai University, Sujeeth Pareddy from BITS Pilani, Swadhin Thakker from VJTI and Dhruv Joshi from LG Prasad Eye Institute, has been working on the project since July last year.

“The tests for sleep apnea in a hospital are very expensive. A single night’s test can cost anywhere from Rs 8,000-15,000. ARAM solves that problem as the patients can now monitor themselves at home,” said Gupte. The team has built the prototype for Rs 30,000 and hopes to make it even more affordable in future.

With five kinds of sensors, ARAM is a wearable, reusable diagnostic mask for mass-screening at home. As a part of their research, the team of six engineers conducted a Harvard-recommended survey to diagnose sleep apnea in 200 professionals in Powai.

“We found in our sample, which consisted of people 20-40 years of age, that 83 per cent of people did not know about sleep apnea and 34 per cent of them showed symptoms of suffering from it,” said Trivikram Annamalai, a Masters student of Industrial Design Centre at IIT Bombay. With the testing already underway at Hinduja Hospital, the team is now in talks with the Seven Hills hospital in Andheri (E) for further testing.

Various sensors are present within the mask of ARAM, including pressure censor, microphone to measure snoring level and accelerometer to measure body movement. It can be worn through the night as the captured data is uploaded on a server. The data is then sent to a doctor online, who can recommend the treatment. “We have been testing ARAM with the state-of-the-art equipment at Hinduja, which has more sensors. By comparing the two, we can develop our prototype better,” said Gupte, a PhD student in Aerospace Engineering, IIT-Bombay.


♦ Sleep apnea is a type of sleep disorder characterised by pauses in breathing or instances of shallow or infrequent breathing during sleep.

♦ Each pause in breathing, called an apnea, can last for several seconds to several minutes, and may occur 5 to 30 times or more in an hour.

♦ When breathing is paused, carbon dioxide builds up in the bloodstream. Chemoreceptors in the blood stream note the high carbon dioxide levels. The brain is signaled to wake the person sleeping and breathe in air.
